I've been having no luck for the past 3 months with containing my ants in their outworlds by using fluon on a vertical surface, so I think I'm going to need an upside-down lip surface to apply it to, like this:
It seems that containers with upside-down lips to apply your deterent on are very scarce - AntsCanada has them (picture above) but I don't want to pay 100 dollars for each outworld. AntStore has super nice looking add-on lips and outworlds, but they won't ship outside of Europe (sometimes even out of Germany), damn that.
I'm having so much trouble with feeding my ants lately as my colonies are growing in their tubes. I get escapees almost every time I open their tubes to feed them and it's a real problem. They are walking over fluon vertically like it's nothing (no matter how I apply it or what kind of surface I apply it to, glass or plastic) and it's getting to be a real setback, especially as of the last day ever since I came back from vacation and my colonies are 5 times bigger and getting nearly impossible to feed without their outworlds.
I feel like the other barriers (Olive oil, vaseline, talcum powder, etc.) will do just as bad since fluon is considered the top barrier, but I'll try them out if I get the chance. I might have some of that stuff lying around the house.
So does anyone know of or suggest any containers/outworlds with an inside lip excluding the ones from AntsCanada and Antstore? Or any other suggestions/help with my barrier troubles? Thanks!
